Body Composition and Sarcopenia Indicator among Elderly in the Nursing Home

Abstract

: Sarcopenia is definite as the age-related loss of muscle mass and muscle function with the highest prevalence was reported in institutionalized older adults. Body composition consisted of many compartments of muscle mass and types of fat mass. This study aims to analyse the association between body composition (muscle mass and fat mass) and physical performance as sarcopenia indicator among elderly in the nursing home. We examined the skeletal muscle mass index (SMI), grip strength (GS) and walking speed (WS) as sarcopenia indicator. For muscle mass area, we measured whole, arms, legs, and trunk skeletal. We also measured body fat, visceral fat, and subcutaneous fat as component of fat mass. A total of 54 elderly (75.9 % was female) participated with mean age was 71 ± 8.2 years. The prevalence rates of sarcopenia were 98% based on three indicators of sarcopenia. Almost of muscle mass areas except trunk were associated with SMI and GS, meanwhile all areas of subcutaneous fat were correlated with GS. Among elderly nursing home, the prevalence of sarcopenia was high. Muscle mass area and subcutaneous fat was correlated with sarcopenia indicators.
